Arneburg Biomethane Refinery

After a building time of only eight months, one of Germany's largest biomethane refineries went live in the Altmark Industrial and Commercial Zone and has been supplying the public grid since May 2013. With four digesters of 4,900 m³ and six digestate storage tanks of 5,000 m³ the plant produces 1,650 standard m³ of raw biogas an hour. 200 m³ of this raw gas are used for the heat needs of the plant.
By means of chemical amine treatment, the gas is converted into about 700 standard m³ of processed biomethane an hour, with a methane content of 99 percent – enough to supply 5,000 homes with power and heat. A solid matter input system is used to supply the stainless-steel digesters with about 70,000 t of substrates a year.
